How does scene security contribute to an investigation?

Scene security plays a crucial role in an investigation by preserving evidence that may be vital to understanding the incident in question. When a crime scene or any investigative scene is properly secured, it restricts access to only those individuals involved in the investigation. This limits the risk of contamination or loss of evidence, such as fingerprints, DNA, or any physical items relevant to the case. By maintaining the integrity of the scene, investigators can ensure that the evidence collected is reliable and can be used effectively in legal proceedings. Preserving evidence is a fundamental part of the investigative process, as it allows for accurate reconstruction of events and supports the overall validity of the findings.
